The number of covalent bonds in fluorine molecule is

A)  2              

B)  3

C)  1              

D)  5

Correct Answer: C

Solution :

 The electronic configuration of fluorine atom is\[{{F}_{(9)}}-1{{s}^{2}},2{{s}^{2}}2{{p}^{5}}\] So, fluorine required only one electron to complete its octet. Thus, in the formation of  fluorine molecule only one covalent bond  formed.
